It is possible to swipe multiple ListView Cells to see the context actions.
Steps to reproduce:
1. ListView with ContextActions
2. Swipe multiple Cells at the same time
3. tap the context action button
4. Action is applied to other cells then the selected one
- It shouldn't be possible to swipe more than one cell at a time
I can somewhat confirm.
On iOS10 devices, when trying to swipe the second cell, it crashes and raises an System.ArgumentNullException with the message:
Value cannot be null.
Parameter name: gestureRecognizer
It originates from UIKit.UIView.RemoveGestureRecognizer, from what I can tell.
Using Forms 18.104.22.168 it seems to work on iOS 9 devices.
@Xet: you were supposed to open a new bug for the crash. It's important. couldn't find one... did you do it?
No I did not, since I figured that the issues reported in the bug is directly related to the crash.
I confirm the behaviour described by @Xet on iOS 10 devices.
Reproduced Xet. Opened "ContextActions List Gallery" on iOS > Open context actions for one row > Try open context actions for another. Observed exception.
The second bug you all are describing should soon be fixed. See https://github.com/xamarin/Xamarin.Forms/pull/442. I'm wondering if the first comment indicates another bug.
Should be fixed in 2.3.4-pre2
